Thanks Roger I've been overwhelmed by the number of responses too this image, first ever over 300 view's on CN, you may be right just do it as I see fit and let the viewee's be the judge
Trevor, I want to comment on what I think is good about the image. Colour I think is best sorted by doing a auto colour in PS and see how that presents. If it ends up too green look around at other peoples examples, find one you like and then work towards that image colour.
That said, I think the focus is good, some selective sharpening via a mask will help sharpen some areas and keep the stars natural looking. Go to Ken Crawford's site and check out his tutorials on slective sharpening. This is a technique worth learning.
I think the detail is very good but you could have gone for 10 minute subs to increase the depth of detail. There is plenty of smooth nebulosity in your image so you are on the right track.
Overall I think the image is good but could do with some refining. Perhaps start from scratch and see how you go with the colour and sharpening.
The Tarantula I found is the toughest image I have worked on to date. It is hard to get everything right. Your guiding helps to make this image look good. Stars only have to look just slightly elongated on this target and then everything looks wrong. Keep at it, your images are improving all the time and in 1 year you have come a long way.
can never please everyone else
